   The sensor supply voltage

2. 2

   The manifold air pressure sensor

3. 3

   The variable fan speed sensor

1. 1

   Check the sensor supply voltage

   Verify the voltage level using a multimeter to ensure it is within the specified range.

2. 2

   Inspect the manifold air pressure sensor

   Look for signs of damage, loose connections, or incorrect installation.

3. 3

   Inspect the variable fan speed sensor

   Check for physical damage, wiring issues, or improper mounting.
